Amazon Appstore Apps & Coins

A couple of questions. Will apps I have already purchased in the Amazon App Store work on this. Will I need to repurchase apps for my phone to use on this? Are the Fire TV apps just better and will only run on the Fire TV, but my regular app store apps still useable on this? This is a pretty big deal as I have roughly 300 apps & games purchased or FAOTD from Amazon.

Another question is about the coins. I somehow accumulated 270 coins on my account. I don't know how I did this, but now I know they are like credits, which is cool. Did anyone else get these?

I imagine apps/games you already have purchased through Amazon will be made available on your Amazon FireTV without additional purchase. If you go to a Fire TV app or game page you can see a list of your compatible devices. Even though Fire TV won't be shipping until tomorrow, many of these games show us available for download on my Kindle Fire, which is why I'm making this assumption.

I didn't get any extra coins... you must have earned them over the course of those 300+ purchases! I'm interested to hear more about the coins too.
